this usually means that the motherboard or the power supply has failed
to test the power supply do a "BIST" by removing the power supply and then connecting the power cable to it
the green led behind the rear fan should be on and the fan needs to be spinning, if its not spinning or red ,....the supply is bad

reread what i wrote,........i stated that the light inside the power supply by the rear fan should be green, and if red that means the pwr supply has failed the fan also must be spinning, a non spinning fan also means a failed power supply...got it now?
